General Safety Instructions
Before operating the instrument, review the following safety precautions to avoid
injury and prevent damage to this product or any products connected to it.
Service procedures should be performed by qualied personnel only!
Do Not Operate Without Covers! To avoid electric shock or re hazard, do
not operate this product with covers or panels removed.
Do Not Operate in Wet or Damp Conditions! To avoid electric shock, do not
operate this product in wet or damp conditions.
Do Not Operate in an Explosive Atmosphere! To avoid injury or re hazard,
do not operate this product in an explosive atmosphere.
Do Not Disconnect Connectors! To avoid damage of the instrument never
disconnect any connector while the device is ON.
Do Not Operate With Suspected Failures! If you suspect there is damage to
this product, have it inspected by qualied service personnel.
Ground The Instrument! The instrument is grounded through the Protective
Earth lead of the power cord. To avoid electric shock, it is essential to connect
the earth terminal of power cord to the Protective Earth terminal before any
inputs or outputs.
Do Not Insert Anything into the Holes of Fan! Do not insert anything into
the holes of the fan to avoid damaging the instrument.

PUMA – User Manual General Safety Instructions
Use Proper Power Cord! To avoid re hazard, use only the power cord spec-
ied for this product.
Check Connectors! Do not operate the instrument if all connectors are not
properly plugged.
Heavy instrument! Due to the weight of the instrument it is strongly rec-
ommended to manipulate it with assistance of another person.
Use Proper Mains Voltage! Do not operate this product from a power source
that is outside of the specied voltage range.
Use Proper Fuses Only! Do not use fuses which are not specied by the
manufacturer. If a fuse with a different characteristics or value is used, the
protection is not effective.
Operator’s Training! Operator should be familiar with operation of the in-
strument and Safety Regulations.
Use Manufacturer’s Cables Only! Other devices can be connected to the
instrument via the appropriate cables only.
Do not drop the product and do not expose it to any major shocks!
Do not operate the product outside the power limits given in the speci-
cations!
Keep the packaging material out of the reach of children to prevent the
risk of suffocation!
Unstable or highly disturbed AC power may invoke safety circuits to protect
the sensitive electronic parts by switching OFF the instrument or burning
inner fuses.
Dispose of packaging material immediately according to locally applica-
ble regulations. However, it is recommended to keep the shipping box
and inner foams in case of necessity to send the instrument to AGICO for
repair.

ture -20 ◦C to + 55 ◦C and relative humidity up to 80 %. The instrument must be
stored at suitable place, free of dust and chemical evaporation. Handle with care!
Instrument is heavy.

PUMA – User Manual PUMA Introduction
1 PUMA Introduction
The PUMA is designed as a precise high eld impulse magnetizer. Inner diame-
ter of magnetization coil is 41 mm which allows to magnetize standard-sized pa-
leomagnetic specimens in any orientation. PUMA enables to impart isothermal
remanent magnetization (IRM) to specimens in the wide range of intensities of
magnetic elds from 1 mT up to 5 T. The elaborate design of the instrument pro-
vides precise setting of the pulse intensity as well as high homogeneity of the eld
over the entire specimen volume.
1.1 Principle of operation
PUMA uses the well-known principle of charging high quality foil capacitors de-
signed for pulsed discharge and then discharging them into a magnetizing coil.
The principal schematics of the instrument is shown on Fig. 1.
The control of the entire magnetization process by the microprocessor ensures
precise pulse triggering at voltage which is calculated with respect to the desired
pulse intensity and the instantaneous temperature of the magnetizing coil. Ac-
counting for the coil temperature signicantly improves the repeatability of the
eld strength. A number of safety features as well as oversized high grade electri-
cal components ensure the safety and reduce the likelihood of serious malfunction
or damage.
